Redox titration of vitamin C in milk powder using the double Au-ring electrode
Summary
Vitamin C is an important antioxidant included in milk powder. The double Auring electrode provides an excellent titration curve when using 2,6-dichlorophenolindophenol (DPIP) as titrant and is easy to clean.
With the OMNIS system, a fast and accurate determination of vitamin C in milk powder by a bi-voltametric titration is realized.
